DESCRIPTION D'EXEMPLES DE REALISATION DE L'INVENTIONDESCRIPTION OF EXAMPLES OF EMBODIMENT OF THE INVENTION

La Figure 2 montre un élément 1' absorbant d'énergie perfectionné selon l'invention particulièrement adapté à la construction de sièges d'hélicoptère.The Figure 2 shows an element 1 'improved energy absorbent according to the invention particularly suitable for the construction of helicopter seats.

Cet élément 1' est muni d'une portion absorbante 2, d'un premier point d'ancrage 3 et d'un deuxième point d'ancrage 4, une première et une deuxième extrémités distales 2', 2" de ladite partie absorbante 2 étant respectivement solidarisées aux premier et deuxième points d'ancrage 3, 4.This element 1 'is provided with an absorbent portion 2, a first anchoring point 3 and a second anchoring point 4, first and second distal ends 2', 2 "of said absorbent portion 2 respectively being secured to the first and second anchoring points 3, 4.

La portion absorbante 2 comporte deux éléments filiformes 5, 6 solide se déformant élastiquement lors d'une sollicitation en traction inférieure à un seuil prédéterminé et plastiquement lors d'une sollicitation en traction supérieure audit seuil prédéterminé.The absorbent portion 2 comprises two filiform elements 5, 6 solid elastically deforming during a tensile stress below a predetermined threshold and plastically during a tensile stress greater than said predetermined threshold.

Ces éléments filiformes 5, 6 sont munis d'une succession de segments droits 7, 8, 9 et de segments en arc de cercle 10 de manière à avoir au moins deux segments droits successifs reliés par un segment en arc de cercle 10.These filiform elements 5, 6 are provided with a succession of straight segments 7, 8, 9 and segments in an arc of circle so as to have at least two successive straight segments connected by an arcuate segment 10.

Une bride 12 de précontrainte est installée entre la première 2' et la deuxième 2" extrémité distales correspondant respectivement aux segments droits 8 et 9 les plus éloignés l'un de l'autre de l'élément 1'. La bride 12 est également positionnée entre les deux éléments filiformes 5, 6.A preloading flange 12 is installed between the first 2 'and the second 2 "distal end respectively corresponding to the straight segments 8 and 9 farthest from each other of the element 1 '. The flange 12 is also positioned between the two filiform elements 5, 6.

De préférence, la bride 12 est positionnée au centre de l'élément absorbant d'énergie 1, c'est-à-dire qu'elle est positionnée suivant un axe de symétrie X de l'élément absorbant 1'.Preferably, the flange 12 is positioned in the center of the energy absorbing element 1, that is to say that it is positioned along an axis of symmetry X of the absorbent element 1 '.

Cette bride 12 présente une longueur L supérieure à l'écart E entre les deux extrémités distales 2', 2" de manière à précontraindre ledit élément absorbant 1'. Cet écart E correspond à la distance qui sépare les segments droits d'extrémité 8 et 9 lorsque l'élément 1 n'est pas précontraint.This flange 12 has a length L greater than the distance E between the two distal ends 2 ', 2 "so as to prestress said absorbent element 1. This gap E corresponds to the distance that separates the straight end segments 8 and 9 when the element 1 is not prestressed.

Comme bien visible sur la vue en coupe longitudinale de la Figure 2, la bride 12 présente sensiblement la forme d'une tige allongée terminée à ses extrémités 13 par deux éléments bloquants. Ces éléments bloquants sont conçus pour garantir le maintien en position de l'élément absorbant d'énergie 1' sans avoir un risque de repli de celui-ci.As clearly visible on the longitudinal section view of the Figure 2 , the flange 12 has substantially the shape of an elongated rod terminated at its ends 13 by two blocking elements. These blocking elements are designed to ensure the holding in position of the energy absorbing element 1 'without having a risk of folding it.

A cet effet, les éléments bloquants sont formés chacun par deux rebords 13.1, 13.2 délimitant une cuvette pour recevoir les extrémités distales 2', 2" de l'élément absorbant 1', les rebords 13.1, 13.2 étant destinés à venir en appui contre des côtés des extrémités distales 2', 2" afin de limiter le déplacement possible de la bride 12 suivant une direction perpendiculaire à la direction longitudinale de l'élément absorbant 1'.For this purpose, the blocking elements are each formed by two flanges 13.1, 13.2 delimiting a bowl for receiving the distal ends 2 ', 2 "of the absorbent element 1', the flanges 13.1, 13.2 being intended to bear against sides of the distal ends 2 ', 2 "in order to limit the possible displacement of the flange 12 in a direction perpendicular to the longitudinal direction of the absorbent element 1'.

La Figure 2 fait également apparaître que l'épaisseur K1 de la partie 22 de la bride 12 qui s'étend entre les deux extrémités 13 est inférieure à l'épaisseur K2 de chacune des extrémités 13.The Figure 2 also shows that the thickness K1 of the portion 22 of the flange 12 which extends between the two ends 13 is less than the thickness K2 of each of the ends 13.

La bride 12 est conçue pour ne pas flamber aux efforts exercés par l'élément absorbant d'énergie 1'. A cet effet, l'épaisseur K1 de la bride 12 est fonction des efforts de compressions exercés par l'élément absorbant d'énergie 1 sur la bride 12.The flange 12 is designed not to flare at the forces exerted by the energy absorbing element 1 '. For this purpose, the thickness K1 of the flange 12 is a function of the compressive forces exerted by the energy absorbing element 1 on the flange 12.

En outre, la longueur L de la bride 12 est fonction du niveau de précontrainte exigé par l'élément absorbant d'énergie 1 pour le fonctionnement souhaité.In addition, the length L of the flange 12 is a function of the prestressing level required by the energy absorbing element 1 for the desired operation.

Le maintien de la bride 12 est réalisé par les efforts F de compression exercés par l'élément absorbant d'énergie qui a tendance à vouloir retourner dans la position dans laquelle l'élément n'est pas contraint.Maintaining the flange 12 is achieved by the compression forces F exerted by the energy absorbing element which tends to want to return to the position in which the element is not constrained.

Les segments droits 7, 8, 9 sont sensiblement parallèles entre eux lorsque aucun effort de précontrainte n'est appliqué par la bride 12 sur l'élément absorbant (cf. Figure 1), et forment un léger angle avec une direction B perpendiculaire à la direction longitudinale de la bride 12 lorsque l'élément est précontraint par la bride (cf. Figure 2). La direction B se situe dans le plan dans lequel s'étendent les éléments filiformes 5, 6.The straight segments 7, 8, 9 are substantially parallel to each other when no prestressing force is applied by the flange 12 on the absorbent element (cf. Figure 1 ), and form a slight angle with a direction B perpendicular to the longitudinal direction of the flange 12 when the element is prestressed by the flange (cf. Figure 2 ). The direction B lies in the plane in which the filiform elements 5, 6 extend.

On note que les points d'ancrages 3 et 4 gardent les mêmes fonctions que pour un élément absorbant d'énergie 1 non précontraint.It is noted that the anchoring points 3 and 4 retain the same functions as for a non-prestressed energy absorbing element 1.

Comme montré sur la Figure 3, un siège d'hélicoptère comporte un montant 19 conçu pour intégrer deux axes 15, 16 coopérant avec les points d'ancrage 3, 4 de l'élément absorbant d'énergie 1'. Plus précisément, l'axe 16 est un axe fixe coopérant avec le point d'ancrage 3. L'axe 15 est un axe mobile coulissant dans une glissière du montant 19, cet axe 15 étant relié à un baquet référencé 20.As shown on the Figure 3 , a helicopter seat comprises an amount 19 designed to integrate two axes 15, 16 cooperating with the anchoring points 3, 4 of the energy absorbing element 1 '. More specifically, the axis 16 is a fixed axis cooperating with the anchoring point 3. The axis 15 is a movable axis sliding in a slide of the upright 19, this axis 15 being connected to a tub referenced 20.

Le procédé consiste après avoir assemblé tous les éléments composant le siège, de précontraindre l'élément absorbant d'énergie 1' à l'aide d'un outillage spécialisé 17 dans le but d'insérer une bride 12 dans la glissière du montant 19 bloquant l'axe mobile 15 en position.The method consists, after having assembled all the elements making up the seat, of prestressing the energy-absorbing element 1 'with the aid of specialized tools 17 in order to insert a flange 12 into the slide of the blocking post 19 the movable axis 15 in position.

Une fois montés sur le siège, les axes 15 et 16 ont la caractéristique de pouvoir s'adapter sur l'outillage spécialisé 17 permettant d'exercer un effort de précontrainte afin de réaliser l'étape de mise en place de la bride de précontrainte 12.Once mounted on the seat, the axes 15 and 16 have the characteristic of being able to adapt to the specialized tooling 17 making it possible to exert a prestressing force in order to carry out the step of placing the prestressing flange. .

L'avantage associé à la précontrainte de la bride 12 est l'amélioration des performances de l'élément absorbant d'énergie 1 selon l'état de la technique notamment dans ses applications décrites dans le document EP-2113677 .The advantage associated with the prestressing of the flange 12 is the improvement of the performance of the energy absorbing element 1 according to the state of the art, in particular in its applications described in the document EP-2113677 .
